3 Description

The SN75LVPE3410 is a four channel low-power

high-performance linear repeater or redriver designed

to support PCI Express (PCIe?) Generation 1.0, 2.0

and 3.0.

The SN75LVPE3410 receivers deploy continuous

time linear equalizers (CTLE) to provide a

programmable high-frequency boost. The equalizer

can open an input eye that is completely closed

due to inter-symbol interference (ISI) induced by

an interconnect medium, such as PCB traces. The

CTLE receiver is followed by a linear output driver.

The linear datapaths of SN75LVPE3410 preserve

transmit preset signal characteristics. The linear

redriver becomes part of the passive channel that

as a whole get link trained for best transmit and

receive equalization settings. This transparency in

the link training protocol result in best electrical

link and lowest possible latency. The programmable

equalization of the device along with its linear

datapaths maximizes the flexibility of physical

placement within the interconnect channel and

improves overall channel performance.

The programmable settings can be applied easily

through software (SMBus or I2C) or by using pin

control.
